I have just installed Red Hat AS 2.1 but I cannot open a ftp session to the server.

What should I config in the sever to allow users to open a ftp session?

Hi

FTP is not enabled by default, you need to do the following

Install the ftp rpm(wuftpd)
Enable ftp

Then ftp will start working

No reboot is required install ftp rpm,then enable it using setup, do a kill -HUP on inetd and ftp will start working

Hope this helps

Tonatiuh,

I hope you get some help on this forum. I know you will. There are many talented peple on this forum and I owe a lot of what I have learned to them.

How about assigning them some points for the effort. Not for me but for the others. I dont have a clue.

Hi Tonatiuh,
there is probably
1. no FTP server instalation on your box or 2.ftp server is not started or
3.your system is using ftp server via superserver or superdaemon - inetd or xinetd

1) check whether ftp is installed

rpm -qa | grep -i ftp

installation is done by

rpm -Uvh package.rpm (I'm using pure-ftpd)

2)start ftp daemon
/etc/init.d/your_ftp_server start

automatic start in boot you will achieve by

chkconfig --level 35 on pure-ftpd

where numbers are system levels
(try chkconfig --list )

3)you must find out which superserver is running on your box

ps -ef | grep inet

you should see something like this
......... 00:00:00 /usr/sbin/xinetd
or
....................../usr/sbin/inet

than you must allow ftp service in configuration file of superserver.

vi :/etc/xinetd.d/pure-ftpd

disable = no

or

vi /etc/inetd.conf

delete # on the begining of ftp rows

finnaly you have to restart superserver

xinetd restart

or

inetd -c

hope this will help

I am really confused.

Does not RH have its own FTP server which just need to be activated and ready (similar to TelNet) ?

I have searched for the files all of you have told, but when I downloaded and try to install it, it says that has dependencies and the dependecies (downloaded) say that are from diferente architecture.

Is there any site to donwload all the files just for the RH AS distribution?

Could you helpe giving me the proper links to download the files you have mentioned?

Re: FTP

Jan Sladky — Tue, 02 Nov 2004 17:42:56 GMT

try

rpm -qa | grep -i ftp

and you will see whether is ftp server instaled or not

try to install from original AS CD, you should have it
or try redhat.com downloads

This is the output of the command

[root@RAC1 etc]# rpm -qa | grep -i ftp
gftp-2.0.8-2
ftp-0.17-12
ncftp-3.0.3-6

Re: FTP

Tonatiuh — Tue, 02 Nov 2004 17:56:48 GMT

I think I should wait until my problem be solved to assign points. At this moment, the answers have been not complete (to my out of experience) and my problem is not solved. So that I cannot assign points to answers which do not really help me.

RH AS/ES comes with FTP servers, but unless you choose to install them at install time, they don't go on.

As all Enterprise RH products install 'ssh' by default, the assumption is that you neither need or desire telnet or ftp (unsecure and un-encrypted protocols).

You can download the 'wuftpd' package from the RedHat Network secure website (you've created a RHN account, yes?), or you can chose to use the 'vsftpd' package instead (more secure).

I can't give you URL's to these as they change per login user.

If you haven't created a RHN account, then you should do so immediately.

Without an RHN account, you only have access to Source RPM's on the RH FTP site (ftp.redhat.com). If you have to go down this path, you'll also need the development packages installed.

This is only necessary of course if you do not have the installation media available.

Once you have the package, it's very easy to install (follow Jan's advice).

I suppose that easiest way for you is GUI installation tool accesible from KDE/GNOME menu.
I don't know the name of the tool , I'm using SuSE distro, but know it exists, I was using it several months ago. There select some ftp server.

You can also downloads pure-ftpd from

http://rpm.pbone.net/index.php3/stat/4/idpl/1129356/com/pure-ftpd-1.1.0-1.i386.rpm.html
(rpm)

or source from

http://sourceforge.net/projects/pureftpd/
(It is bz2, => I'll need to compile it:
bzip2 -d file

cd file
./configure
make
make install)

Insert and mount a cdrom.
The rpm files should be on a cdrom under
/RedHat/RPMS/*

the command:
rpm -Uvh mountpoint/RedHat/RPMS/wu-ftpd-version.rpm

where mountpoint is the point where the cdrom is mounted, and version is the version of wu-ftpd on your cdrom - will install the ftp server on your RedHat.
From the output you gave us-it seems that currently you have ftp clients installed ,but no server.
After successfull installation of FTP server.
run the command:
chkconfig wu-ftpd on

This will enable and start the FTP service.
After that you can try to ftp to this server.

As alternative you can try to install the vsftpd server from the same set of CDROMs.

Thanks Alexander! I have successfully installed and activated the wu-ftpd.

But I can not ftp with root user, only with anoterh users.

Re: FTP

Johannes Krackowizer_1 — Wed, 03 Nov 2004 12:59:13 GMT

hi,

there are some files in /etc/. i'm not sure but i think the are named ftpacces or something like that. you have to remove root from this file to allow root ftp access.

best regards,

johannes

Jan Sladky — Wed, 03 Nov 2004 13:59:04 GMT

Hi,
In order to root can use ftp, you must delete
root from /etc/ftpusers

Re: FTP

Tonatiuh — Wed, 03 Nov 2004 14:13:58 GMT

/etc/ftpusers says:

# The ftpusers file is deprecated. Use deny-uid/deny-gid in ftpaccess.

I do not underestand how to config the ftpaccess to user root gain ftp acces?

Anoyone who can help me?

Re: FTP

Johannes Krackowizer_1 — Thu, 04 Nov 2004 04:20:16 GMT

hi tonatiuh,

if you edit /etc/ftpaccess:

1) delete deny-gid and deny-uid lines
2) add allow-gid %1-10000 and allow-uid %1-10000

allow-gid %1-10000 means that all groups with id from 1 to 10000 are allowed to log onto ftp-server.

allow-uid %1-10000 means that all users with id from 1 to 10000 are allowed to log onto ftp-server.

root has group root.
user root's uid (user id) is 1.
group root has gid (group id) 1.

best regards,

johannes
